Abstract: The control of dengue fever/dengue haemorrhagic fever (DF/DHF) in Singapore is largely through source reduction, health education and law enforcement. Adulticiding is carried out when the house index exceeds 2%, and when there is a reported case or a localized outbreak. Regular Aedes surveillance is conducted in areas identified as dengue-sensitive. The national annual Aedes house index has been kept below 2% since 1979; however, the number of cases has seen an increase since 1986. Data for the first four months of 1997 showed that landed properties, schools, construction sites and vacant premises were the main premises-types breeding Aedes mosquitoes. The commonest habitats indoors were ornamental containers, domestic containers, receptacles exposed to rain, canvas sheets and roof gutters. In the public areas, discarded water-bearing receptacles were the major culprit. The Ministry of the Environment, Singapore, which is responsible for dengue control, is constantly looking for permanent ways of eliminating potential breeding habitats. It is also educating householders, construction contractors, estate managements and schools on measures to prevent mosquito breeding in their premises through the mass media, seminars and exhibitions. Enforcement action is stringently carried out. Research to explore new tools to monitor the Aedes population and forewarn about an outbreak is under way. There is a need to establish a reliable population indicator for Aedes breeding found in the open areas outside of premises, as the present premises indices do not include these.
